Validasi metoda pengukuran kadar air perisa bubuk menggunakan moisture analyzer halogen Hb43-S, sebagai alternatif metoda oven dan karl fischer.

Abstract

In seasoning industries, moisture content of the product is one of important parameters to be measured and reported to assure the food product quality. The common analysis method to measure it in the food industry is Loss on drying (LOD) method by oven and Karl Fischer method. The result of LOD method is recognized as moisture content, while the result of Karl Fischer method commonly known as water content. The method that preferably used by PT. Givaudan Indonesia is Loss on drying method. This research aimed to obtain the heating conditions (temperature) in Moisture Analyzer Halogen HB43-S which can make the analysis result of this equipment will close to the result of LOD method using oven UM-400. The data obtained will be tested statistically using Dunnett Test method that compare these with the control. The result revealed that the use of Moisture Analyzer HB43-S at 105oC provided similar result to oven UM-400 method, however the use of oven methods is still more efficient rather than using Moisture Analyzer for the higher number of samples that more than 30. Moisture analyzer efficiently used for the limited samples only. Base on this research result we will use Moisture Analyzer method for handling the urgent request only. Karl Fischer method suitable for derivate sucrose products, it is able to replace oven analysis to measure vanilla flavour. This validation is needed to give information and data that can be used to expedite the approval of products.
